The dinuclear title compound, [Co(2)Cl(3)(C(6)H(4)NO(2))(C(6)H(6)N(2)O)(2)(C(2)H(5)OH)], contains two six-coordinate Co(II) atoms with different octa-hedral coordination environments. One Co(II) atom is coordinated by two N atoms from one pyridine-2-carbaldehyde oxime ligand, by one terminal and one bridging Cl(-) ion, by one O atom from an ethanol mol-ecule, and by one O atom from a bridging p...

In the title dinuclear ionic complex, [Cd(2)(C(4)H(4)N(2))(H(2)O)(8)][Cd(2)(CH(3)CO(2))(8)(C(4)H(4)N(2))], the cation and anion are disordered equally over a site with symmetry mmm. The Cd(II) ions and the N atoms of the bridging pyrazine ligand lie on the inter-section of two crystallographic mirror planes. The C atoms of the bridging pyrazine ligand lie on one of these mirror planes, and the ...

The slow dissociation of DNA threading intercalators makes them interesting as model compounds in the search for new DNA targeting drugs, as there appears to be a correlation between slow dissociation and biological activity. Thus, it would be of great value to understand the mechanisms controlling threading intercalation, and for this purpose we have investigated how the length of the bridging...

The title complex, [Cu(4)I(4)(C(21)H(15)N(3))(2)], lies on an inversion centre located at the centroid of a four-membered ring formed by one of the crystallographically independent Cu(I) ions and a triply bridging iodide ligand. The 2,2':6',2''-terpyridine (phterpy) ligand chelates each of the independent Cu(I) centres in a bidentate fashion, with the N atom of the central pyridyl ring bridging...

1,2-Dithiooxalate (dto) can be employed as a bridging ligand and gives symmetric ( O , S -chelation) or asymmetric - coordination modes. In this study, we have prepared novel dto-bridged diiron(II)...

In the title complex, [Cu(NCS)(C(12)H(8)N(2))](n), the Cu(I) ion is in a distorted tetra-hedral CuN(3)S coordination geometry. The thio-cyanate ligand acts as bridging ligand, forming chains along [100]. A crystallographic mirror plane runs through the Cu(I) ion, the thio-cyanate ligand and the middle of the phenanthroline ligand.

A facile synthesis of a new bisoxazoline ligand is described. This ligand contains a urea bridging unit and is capable of stabilizing bimetallic complexes. An X-ray crystal structure of a bis-copper complex is reported.

A combined experimental and theoretical approach has been used to investigate the redox properties of two dinuclear Ru(II) complexes, 2a and 2b, containing the planar dpt-ph-dpt bridging ligand (dpt-ph-dpt = 1'',4''-bis(2,4-dipyrid-2'-yl-1,3,5-triazin-6-yl)benzene). The redox properties of the free bridging ligand and the X-ray structure of 2a have also been reported, together with the X-ray st...

The synthesis, spectroscopy and magnetic characterization of five new dinuclear copper(II) complexes are described. All five compounds have the general formula [Cu2(L)4(O-R)2](Cl)2 or [Cu2(L)2(Cl)2](Cl)2, in which R = CH3 or H, L=2, 3 or 4-pyridinemethanol as L2, L3 or L4, respectively. The title compounds consist of dinuclear units with bridging methoxo groups in [Cu2(L4)4(O-CH3)2](Cl)2, hydro...

The reaction of rare-earth bis(alkyl) complexes containing a bis(phosphinophenyl)amido pincer (PNP), LnPNPiPr(CH2SiMe3)2 (1-Ln, Ln = Y, Ho, Dy), with ruthenium trihydride phosphine complexes, Ru(C5Me5)H3PPh3 and Ru(C5Me5)H3PPh2Me, gave the corresponding bimetallic Ln/Ru complexes bearing two hydride ligands and a bridging phosphinophenyl (μ-C6H4PPh2-κP:κC , 2a-Ln) or a bridging phosphinomethyl ...
